Pastillage dough, commonly known as gum paste, is a mixture used to make small decorations to put on cakes. It can be made into leaves, swirls, and many other common cake designs. A simple decoration that you can make out of pastillage dough is flowers. The dough can be dyed and coloured to match the style of the cake.
Roll out the pastillage dough on a flat, clean surface with a rolling pin.
Roll a portion of the dough into a small and long rod shape over a small piece of thin wire. This will be the base of the flower. The wire allows you to stick the flowers in the cake and form the flowers while the dough is still wet.
Use the small portions of the dough to mould the desired petals. If making a rose, you should roll out a longer piece and wrap the whole piece around the base of the flower. Start wrapping closely to the base and make it wider to go around the flower. Any other type of flower's petals should be made by hand individually. You may use a small, splinter-free wooden stick to round the edges of the petals.
Attach the petals to the base of the flower by moulding the bottoms of the petals to the bottom of the base. After the base is surrounded by petals, mould another layer of petals to the back of the first row for a fuller flower.
Add texture to the petals by making small and smooth marks with a toothpick. Allow the flowers to dry overnight.
Mold the flowers quickly to avoid cracks in the dough.
Warn the people eating the cake about the wire in the flowers.
